Port Forwarding And Triggering; Remote Computer Access Basics - NETGEAR D6300 User Manual

8. Select the radio button for the IP address setting that you want to use:
• Get dynamically from existing router. The other router on the network assigns an
IP address to this router while this router is in AP mode.
• Enable fixed IP settings on this device (not recommended). Use this setting if you
want to manually assign a specific IP address to this router while it is in AP mode.
Using this option effectively requires advanced network experience.
Note: To avoid interference with other routers or gateways in your network,
NETGEAR recommends that you use different wireless settings on
each router. You can also turn off the wireless radio on the other router
or gateway and use the D6300 only for wireless client access.
9. Click the Apply button.
The IP address of the router changes, and you are disconnected.

Port Forwarding and Triggering

By default, the modem router blocks inbound traffic from the Internet to your computers
except replies to your outbound traffic. You might need to create exceptions to this rule for
these purposes:
• To allow remote computers on the Internet to access a server on your local network.
• To allow certain applications and games to work correctly when their replies are not
recognized by your modem router.
Your modem router provides two features for creating these exceptions: port forwarding and
port triggering. The next sections provide background information to help you understand
how port forwarding and port triggering work, and the differences between the two.

Remote Computer Access Basics

When a computer on your network needs to access a computer on the Internet, your
computer sends your modem router a message containing the source and destination
address and process information. Before forwarding your message to the remote computer,
your modem router has to modify the source information and create and track the
communication session so that replies can be routed back to your computer.
Here is an example of normal outbound traffic and the resulting inbound responses:
1. You open a browser, and your operating system assigns port number 5678 to this
browser session.
2. You type http://www.example.com into the URL field, and your computer creates a web page
request message with the following address and port information. The request message is
sent to your modem router.
Source address. Your computer's IP address.
